1.判断2个时间是否超时

package main

import (
    "fmt"
    "time"
)

func main() {
    //获取1秒后时间
    var NowTime = time.Now().Add(time.Second * 1)
    //循环
    for {
        //判断时间是否超时
        if time.Now().After(NowTime) {
            fmt.Println(NowTime)
            NowTime = time.Now().Add(time.Second * 1)
        }
        //暂停1秒
        time.Sleep(1000000000)
    }
}
